Abstract
Processes to produce tunable mixtures of 1-hexene and 1-octene are described. The process includes contacting a mixture of a 1-hexene catalyst and a 1-octene catalyst with ethylene under conditions sufficient to produce a composition that includes a desired amount 1-hexene and 1-octene are described.
Claims22
A catalyst composition for the production of 1-hexene and 1-octene, the catalyst composition comprising a 1-hexene catalyst and a 1-octene catalyst, wherein the 1-hexene catalyst and the 1-octene catalyst comprise a nitrogen, phosphorous, nitrogen, phosphorous, nitrogen (NPNPN) ligand, and wherein the 1-hexene catalyst comprises a ligand having a structure of:
- where R1 and R2 are the same or different and are selected from the group consisting of (i) C3 to C4 non-cyclic aliphatic groups, (ii) C5 to C10 aliphatic groups which may be cyclic or non-cyclic, linear or branched, substituted or unsubstituted, and (iii) any combination thereof, and wherein n is 0 or 1, and m=n+3.
